AOI is the abbreviation of Automated Optical Inspection. It is a device that uses optical principles and image processing technology for automated inspection. It is mainly used for the detection of PCB (Printed Circuit Board, printed circuit board), and can detect welding quality, component position, defects and other issues. The following is the working principle and technical characteristics of AOI equipment:


working principle:

1. Optical imaging: AOI equipment uses high-resolution cameras to image PCBs and obtain high-definition image data.

2. Image processing: Use image processing algorithms to analyze and process the acquired image data to identify components, welding points, circuits, etc.

3. Detection algorithms: AOI equipment has various built-in detection algorithms that can identify defects such as welding quality, component offset, missing, and misalignment.

4. Alarm and classification: Once an abnormality is discovered, the AOI equipment will alarm and classify the defects to facilitate subsequent processing.


Technical features:

1. High precision: AOI equipment adopts high-resolution imaging system and sophisticated image processing algorithm, which has high detection accuracy.

2. High efficiency: Compared with manual inspection, AOI equipment can achieve rapid, continuous and accurate inspection and improve production efficiency.

3. Multi-function: AOI equipment can detect various problems such as welding quality, component position, defects, etc., and has strong versatility.

4. Automation: AOI equipment realizes automated detection, reduces labor costs, and improves the automation of the production line.

5. Data analysis: AOI equipment can record and analyze detection data to provide a basis for production quality management.


In general, AOI equipment uses optical imaging and image processing technology to realize automated inspection of PCBs. It has the characteristics of high precision, high efficiency, multi-function, automation and data analysis. It is an important quality inspection equipment in the electronics manufacturing industry.
